Title: Process and installation for extraction of sulphur dioxide from flue gases and/or vapours produced by drying
IPC: B01D53/50
Filed: 1978-04-28
Abstract: In order to minimise the content of the acid radical of sulphurous acid in flue gases from thermal power stations and/or in the drying vapours from sugar factories, it is proposed to use the calcium carbonate sludge being formed as a waste product in the juice purification for the production of sugar, in particular beet sugar. In this case, the sludge is diluted with water and then dispersed over a large area into the flue gases and/or vapours to initiate a reaction with the acid radical of sulphurous acid. A plant which can be operated in this way is characterised by a reaction tower which is inserted between the boiler house with the drying gas discharge lines and the stack and which is connected to the sludge take-off of the decanter of the first carbonation stage and downstream of which a drip-off housing for separating the flue gas or vapour gas from sludge and water is provided.

Patent GB-1502075-A (GB)
Title: Method and apparatus for handling a label
IPC: B65C9/18
Filed: 1976-04-28
Abstract: 1502075 Labelling machine; conveying labels HOBART CORP 28 April 1976 [16 June 1975] 17351/76 Headings B8F and B8A A printed label having a pressure sensitive adhesive on one side thereof is removed from a strip of backing material by passing the strip around an edge and is transported to an applicator by a moving endless belt conveyer. In the embodiment shown in Figs. 3 and 7, blank label stock (29) from a reel (27) moves past a photo pick-up (35), Fig. 1 (not shown), which detects the gaps between the labels and determines the label position relative to a print head 37. As the stock moves between the print hammer 37 and the rotating character wheel 40, the hammer is activated to press the label stock and an ink ribbon 42 against the wheel 40. The strip 205 of backing material is then caused to pass around a sharp corner 55 with the result that the label 58 becomes partially detached therefrom. When the position shown in Fig. 7 has been reached, a solenoid 73 is actuated to move a lever 75 to a position such that a pulley 62 at the end of the lever completes the stripping operation and presses the detached label against a plate 81. The label adheres to a belt 60 passing around the pulley 62 and the belt is set in motion to transport the label to a knurled wheel 68. As the belt passes around the wheel 68, the knurled edges (92) push the label off the belt on to a shoot 21 where it is held. The package to which the label is to be applied is then pressed against the label on the shoot 21. This causes the shoot to pivot about a point 23 and actuate a switch 93 which prevents the printing of a further label until the package has been removed. In another embodiment, Fig. 9, the detached label 104 is transported to an applicator 99 by three conveyer belts 108, 110, 111, the label being held between the belts in the manner shown in Fig. 11. The label 104 is stripped from its backing material 85 on activation of a solenoid 129 which causes a pulley 116 to move downwardly.against the tension in the belt 108. At the applicator 99 the label rests on a pair of edges 101 and a nozzle 102 is moved upwardly between the edges to apply the label to the bottom of a package passing above the applicator 99 on a conveyer.

Title: Apparatus for counting and pricing photographic prints
IPC: G03D15/00
Filed: 1972-04-17
Abstract: 1388579 Counting apparatus EASTMAN KODAK CO 17 April 1972 [16 April 1971] 17630/72 Heading G4D The Specification is concerned with the arrangement of a photo-finishers desk for maximum efficiency. In producing photographic prints negative film strips are spliced into a continuous length and prints are made by machine on to a continuous roll of paper. The roll of prints is subsequently inspected and faulty prints are suitably marked. In the arrangement described the roll also has printed on it marks indicating the position of each print and each customer's order on the roll. The invention concerns an arrangement for cutting and counting the prints and for displaying the number of prints in an order. The print roll 24 and the negative roll 40 are mounted on the desk. The prints are intermittently advanced to a cutter 26 by means 86 which senses the individual print marks. A solenoid operated device (not shown), rejects faulty prints to a viewing position 28 in response to the marks thereon while the rest of the prints are stacked at 35. In synchronism the negative roll is fed to a cutter (as described in Application 17633/72), and is cut into strips of four negatives; the strips are stacked and retained at 41. Negative cutting is stopped when a splice is reached. Print cutting is stopped when an order mark is detected on the print roll. As each print is cut a binary counter 118-120 is stepped. When an order is complete, i.e. when automatic cutting stops the operator takes the pile of prints and the bundle of negative strips 41 and places them in an envelope from a dispenser 20. Removal of the negatives operates a switch 14 producing a signal E which shifts the value in the counter to a memory 124-126 and then a signal F which resets the counter and restarts the cutting operation. The memory is read by a binarydecimal decoder 128 and a respective numeral is illuminated on a display 46. The latter is provided with an overlay 48 on which prices are marked, so that the price of the print order is automatically indicated and can be marked on the envelope containing prints and negatives. Whenever a print is rejected a signal reaches a second binary-decimal decoder 182 which illuminates one of lamps 42 to indicate which negative strip in the bundle has to be reprinted.
